"Wings" Of Prey (PC). Watchout Oleg!

[Avimimus]

I think WoP will have a much more favourable kill ratio for the player and considerably faster action (ie. reduced take-offs and navigation).

SoW will have more realistic opponents, more complex ground targets, a campaign environment that is historically accurate and advanced weather modelling (plus a full mission builder and moddability).

So, I don't think WoP is a direct threat to SoW (although it may be very enlightening to see how profitable a 'light' simulation is compared to a proper one).
